Designed and engineered for the enthusiast, this conversion kit offers a complete, plug-and-play R134a upgrade allowing you to properly run A/C in your 24v swapped E30 without sacrificing the OEM look and feel. Using the E36 M3 Denso compressor and our Denso Compressor Manifold, this has been designed to work with the S50, S52, and S54 as well as the M50, M52, and M54 engine and comes complete with a new Denso compressor, CSF parallel flow condenser and SPAL fan, R134a expansion valve, and new R134a lines (inside and out).

Which model/year should I choose?
Select the model (chassis) assigned to your E30 when it left the factory and refer to the mfg. date on the driver's door to ensure the proper line routing.

Which condenser and fan should I choose?
For a complete and proper conversion, we strongly recommend using our new high performance CSF parallel flow condenser and SPAL fan combo for the most efficient A/C system. If you are planning to use your original OEM fan, we recommend using the Nissens condenser.

Do I need to replace my interior lines?
While your original R12 lines can be used, it's highly recommended to replace all rubber lines when converting to R134a to prevent against leaks.

What if my E30 didn't come factory with A/C?
Our products are designed to support factory A/C models; however, to fit them into non-A/C applications you will need to obtain a factory HVAC wiring harness, high-pressure drier return line (64531381740), evaporator (64518391780), and factory interior HVAC box with sensors, control module, thermostat, etc. Additionally, we recommend replacing your OEM hardware with our A/C bracket and hardware kit.
